It should be noted that, the corresponding a plurality of version message of each window, the corresponding Data Identification of data slot information in each version message, the numbering of data slot information in this window for example, after one of them data slot information has loaded, continue to load the numbering of data slot information in this window and add version message corresponding to the corresponding data slot information of numbering after, until all version message in this window have all loaded.

In addition, the same corresponding sign of each window, window number for example, after all version message in current window have all loaded, and OLT equipment receives the response message that ONU equipment sends, automatically load the window number that current window is corresponding and add the version message in the corresponding window of numbering after, until the version message in window corresponding to all data slot information of this version file has all loaded.

Further, before OLT equipment is determined ONU appliance boot failure, ONU equipment receives the loading Indication message that OLT equipment sends.

Wherein, this loading Indication message comprises the size (quantity of the data slot information that this window is supported) of the maximum load window that this OLT equipment is supported and the version identifier (as version number) of this version file.

In addition, when this ONU appliance boot failure, to this OLT equipment, send and load indication response message.

Wherein, this loading indication response message comprises the size (maximum quantity of the data slot information that this window is supported) of the maximum load window that ONU equipment is supported.

Particularly, boot can load according to a minimum window of size coupling of the window of the size of the maximum load window of the OLT equipment support in above-mentioned loading Indication message and the support of ONU equipment, this minimum window is the size of the maximum load window of the ONU equipment support in above-mentioned loading indication response message, this boot is included in the BOOT or BIOS of ONU equipment, for guiding aforesaid operations system to start; For example: if the size of the maximum load window of OLT equipment support is 300 blocks of data frag infos; And the size of the window of ONU equipment support is 500 blocks of data frag infos, due to OLT equipment, not supporting size is the window of 500 blocks of data frag infos, therefore, boot can be mated a size for holding the window of 300 blocks of data frag infos, so that OLT equipment is loaded on ONU equipment by version file by this window; Here just illustrate, the present invention is not construed as limiting this.

S102, at this ONU equipment, receive after the full detail of this version file, ONU equipment receives the loading end that this OLT equipment sends.

Wherein, this loading end comprises the version identifier (as version number) of version file and the size (as the data length of version file) of version file that ONU equipment receives.

Further, after receiving the loading end of this OLT equipment transmission, ONU equipment sends to load to this OLT equipment and finishes response message.

Wherein, this loading finishes the version identifier (as version number) of version file and the size (as the data length of version file) of version file that response message comprises that ONU equipment sends, like this, OLT equipment finishes version identifier (as version number) in response message according to the loading receiving and the size (as the data length of version file) of version file is further determined the correctness of the version file of loading.

Alternatively, this ONU equipment receives the first check information that OLT equipment sends (such as the version identifier of version file or check code etc.), and after receiving the loading end of this OLT equipment transmission, the second check information of this ONU equipment (such as the version identifier obtaining the version file from receiving or check code etc.) is contrasted with this first check information, if both are identical, this version file is write in the FLASH of this ONU equipment, thereby determine the correctness that version file transmits.

Wherein, this first check message can be included in OLT equipment in the loading Indication message of ONU equipment transmission, or is included in OLT equipment in the loading ending message of ONU equipment transmission; Or this first check message part is included in OLT equipment in the loading Indication message of ONU equipment transmission, another part is included in the loading ending message of ONU equipment reception OLT equipment transmission; The present invention is not construed as limiting this.

In addition, ONU equipment, this version file is write after the FLASH of this ONU equipment, restarts.
